So - first off, thanks for the help on my first thread. I'm going to non-fish cycle my tank (50 gallon, just did 50% water change today because of what turns out was probably a bacteria bloom) and it killed my goldfish - lesson hopefully learned. I'll wait it out next time! So, just to be clear, Is the cycle process the same for goldfish as Tropical? (the beginners article seems to be talking about tropical) I DO need to let it cycle..right? How long does it take for bacterial bloom to clear up and is there anything I can do to speed up the process?
